Part Period Balancing

In forecasting, a dynamic lot-sizing technique that uses the same logic as the least total cost method, but adds a routine called look ahead/look back. When the look ahead/look back feature is used, a lot quantity is calculated, and before it is firmed up, the next or the previous period’s demands are evaluated to determine whether it would be economical to include them in the current lot.
